Why not put pictures of the winners and their bots next to the list of winners?

Can I simply connect this and use it without any programming etc? i.e. is there a hardware mode etc?

order a banana pi from www.robomart.com for comparison raspberry pi. Finally I got delivery today . I found that banana pi more thin that raspberry pi.

If you’re starting out with an Arduino, or teaching classes on it, I’d recommend stocking the following basic components - as everything here can be obtained for a very minimal cost and you’ll be able to teach/learn most of the basic types of input and output with various sensors and interface with several basicshields. The tools are important as well! www.robomart.com will be helpfull to all of u. thnks …..and best of luck frnds

Hi, does anybody know which format has the template? or, is it possible to obtain an svg directly from the scanner? Thanks

For users of OS X 10.9+ (Mavericks and later) a detailed description of FTDI driver options can be found here.

This AVC Fest Gave You Lots of Fun to You. Great Robo Cars to See.

Hi There FYI I have one of these little magic BOB and needed to connect via I2C, not SPI I am using this library and it works : https://github.com/SandboxElectronics/UART_Bridge I added FIFOEnable(1); add the end of the begin function in SC16IS750.h to allow receiving strings (otherwise works with 1 character at a time) Hope this helps

Are you using a class 2 SD card or something?

On the page it says there is a 3D model for this part, but i can’t find it in the repo

I receive a the following error code when I verify the sketch provided in the hookup guide under the zip file 52a0dbb8757b7f21158b4567.zip The error message is:

Arduino: 1.6.5 (Windows 7), Board: “Arduino Uno”

C:\Users\ATS\Documents\Arduino\libraries\MPR121Q\main.c: In function ‘main’: C:\Users\ATS\Documents\Arduino\libraries\MPR121Q\main.c:69:2: error: ‘for’ loop initial declarations are only allowed in C99 mode for (int i = 0; i < 5; i++) ^ C:\Users\ATS\Documents\Arduino\libraries\MPR121Q\main.c:69:2: note: use option -std=c99 or -std=gnu99 to compile your code Error compiling.

Does anyone have ideas on what I should do to eliminate this error? Thank you! Mike

Ive tried doing that a couple times too and my wires eventually broke off the jumper pads. I didn’t like the dangling switch either.

I think one of the lessons we are supposed to get from SFE is to take what they give us and run with it. I modified their SFE eagle file to include a DPDT SMD slide switch and a couple leds to indicate voltage (red-5v green-3v3). My FT231x board does exactly what I want it to.

Really wish there was an RC network on the CLR\ pin to ensure the display is blank on power up. Otherwise, it works well.

My FT231x board does exactly what I want it to.

Open-source FTW!

the GPS mouting strategie is interesting! Mounting on gimbal would help but add weight. Double GPS with different orientation would add redundancy but would cost more.

To connect to the Rn-42 to an iOS check out this tutorial =>http://samirlovgren.se/?page_id=1299

Robomaniac, The vertical GPS mounting strategy worked better than I thought it would. I thought that changing from horizontal mounting of the EM506 to vertical mounting would cause the number of satellites in view to drop by 4 or 5, but it only dropped by 1 or 2. So far I have made about a dozen inverted flights with the vertical mounting with consistent, reliable results. Best regards, Bill
